New Post: Resolver assembly file plug-ins in System.Composition (a la DirectoryCatalog)

Hi,
I have the same issue.
Trying to implement kind of plug in architecure using lightweight mef (for wp8.1), and i wonder what is the way to implement DirectoryCatalog with System.Composition?

I want to enable external users to export their own plug ins (of course, based on my interface) and load them dynamiclly, but i can't find a simple way to do this using the ComposistionHost.

Can you please advise?
Thanks!
